DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof.

The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

In general, penetration of a medium by a penetrating device, e.g., a needle, must overcome friction, which can damage the medium or the device and cause an increase in time spent during penetration. In particular, mammalian tissue penetration by a penetrating device, e.g., a hypodermic needle, can induce pain during the injection process, both from the initial piercing of the tissue and the sliding friction of the needle surface against the tissue. See, e.g., Gill & Prausnitz (2007) J. Diabetes Sci. Technol. 1:725-729, which is incorporated herein by reference. In addition, the tissue injection process is associated with an increased risk of infection at the injection site. See, e.g., Hutin et al.

The state of the art has progressed to the point where there is little distinction left between hardware, software, and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. There are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein can be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In some implementations described herein, logic and similar implementations can include software or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein.

In some variants, for example, implementations can include an update or modification of existing software or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation can include special-purpose hardware, software, firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations can be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or otherwise invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of any functional operations described above. In some variants, operational or other logical descriptions herein may be expressed directly as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, C++ or other code sequences can be compiled directly or otherwise implemented in high-level descriptor languages (e.g., a logic-synthesizable language, a hardware description language, a hardware design simulation, and/or other such similar mode(s) of expression). Alternatively or additionally, some or all of the logical expression may be manifested as a Verilog-type hardware description or other circuitry model before physical implementation in hardware, especially for basic operations or timing-critical applications. Those skilled in the art will recognize how to obtain, configure, and optimize suitable transmission or computational elements, material supplies, actuators, or other common structures in light of these teachings.

This application may make reference to one or more trademarks, e.g., a word, letter, symbol, or device adopted by one manufacturer or merchant and used to identify and/or distinguish his or her product from those of others. Trademark names used herein are set forth in such language that makes clear their identity, that distinguishes them from common descriptive nouns, that have fixed and definite meanings, or, in many if not all cases, are accompanied by other specific identification using terms not covered by trademark. In addition, trademark names used herein have meanings that are well-known and defined in the literature, or do not refer to products or compounds for which knowledge of one or more trade secrets is required in order to divine their meaning. All trademarks referenced in this application are the property of their respective owners, and the appearance of one or more trademarks in this application does not diminish or otherwise adversely affect the validity of the one or more trademarks. All trademarks, registered or unregistered, that appear in this application are assumed to include a proper trademark symbol, e.g., the circle R or bracketed capitalization (e.g., [trademark name]), even when such trademark symbol does not explicitly appear next to the trademark. To the extent a trademark is used in a descriptive manner to refer to a product or process, that trademark should be interpreted to represent the corresponding product or process as of the date of the filing of this patent application.

In certain cases, use of a system or method may occur in a territory even if components are located outside the territory. For example, in a distributed computing context, use of a distributed computing system may occur in a territory even though parts of the system may be located outside of the territory (e.g., relay, server, processor, signal-bearing medium, transmitting computer, receiving computer, etc. located outside the territory). A sale of a system or method may likewise occur in a territory even if components of the system or method are located and/or used outside the territory.

Further, implementation of at least part of a system for performing a method in one territory does not preclude use of the system in another territory.

One skilled in the art will recognize that the herein described components (e.g., operations), devices, objects, and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are contemplated. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar is intended to be representative of its class, and the non-inclusion of specific components (e.g., operations), devices, and objects should not be taken limiting.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.

The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “operably coupled to” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components, and/or wirelessly interactable, and/or wirelessly interacting components, and/or logically interacting, and/or logically interactable components.

In some instances, one or more components can be referred to herein as “configured to,” “configured by,” “configurable to,” “operable/operative to,” “adapted/adaptable,” “able to,” “conformable/conformed to,” etc. Those skilled in the art will recognize that such terms (e.g. “configured to”) can generally encompass active-state components and/or inactive-state components and/or standby-state components, unless context requires otherwise.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications can be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to claims containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that typically a disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms unless context dictates otherwise. For example, the phrase “A or B” will be typically understood to include the possibilities of “A” or “B” or “A and B.”

Prophetic Example 1: Manufacture of an Injection System with a Porous Outer Hollow Cylinder, a Nonporous Inner Hollow Cylinder and Two Concentric Plungers Controlled by Microcircuitry

An injection system is constructed with two concentric hollow cylinders forming a penetrating portion and two concentric plungers (e.g., see FIGS. 1 and 2) and controlled by a microprocessor and microcircuitry.

Upon completion of drug delivery, the penetrating portion is retracted by the device and information on the injection is transmitted to a central computer.

The outer hollow cylinder contains pores to allow the outflow of analgesics and lubricants which reduce the pain associated with intramuscular injections. For example, the outer hollow cylinder may be fabricated from stainless steel (SS) by pulling heated SS tubes through circular dies to obtain the desired diameter of the hollow cylinder, and then pores may be introduced in the hollow cylinder by micromachining. Penetrating devices with lateral pores are described (see e.g., U.S. Pat. No. 6,517,521 issued to Ly on Feb. 11, 2003, which is incorporated herein by reference). Processes and technologies to manufacture custom syringes and needles are available (see e.g., CregannaInfoSheet from Creganna-Tactx Medical, Campbell, Calif.) For example, a 19 gauge (0.686 mm inner diameter), 2.54 cm outer hollow cylinder may be manufactured with approximately 0.050 cm diameter pores spaced approximately 0.08 cm apart for the length of the outer hollow cylinder by micromachining. An inner hollow cylinder, approximately 23 gauge (0.641 mm outer diameter), 2.54 cm long is fabricated and inserted in the outer hollow cylinder. Both hollow cylinders are processed by laser cutting and grinding to create a sharp edge tip (see FIG. 1). Stainless steel circular end pieces and collars (or connectors) are produced by micromachining and micro-welded to the ends of the inner and outer hollow cylinders (see FIGS. 1 and 2). The barrel of the device including concentric plungers and the inner and outer reservoirs are fabricated by injection molding from polypropylene. Materials and methods for syringe construction are described (see e.g., U.S. Patent Appl. No. 2010/0179478 by Kobayashi et al. published on Jul. 15, 2010 and U.S. Appl. No. 2007/0083155 by Muller published on Apr. 12, 2007, which are incorporated herein by reference). A touch sensor is attached to the distal end of the device to detect contact of the device with the skin. For example, a Force Sensing Resister is available from Interlink Electronics, Inc., Camarillo, Calif. which signals the microprocessor when the injection device contacts the skin surface. The microprocessor initiates actuation of the outer plunger to drive lubricant and anesthetic through the pores of the outer hollow cylinder to the exterior. For example the lubricant may be polydimethylsiloxane (available from Dow-Corning, Midland, Mich.) and organosiloxanes (see e.g., U.S. Pat. No. 5,911,711 issued to Pelkey on Jun. 15, 1999 which is incorporated herein by reference), and the anesthetic may be Lidocaine Hydrochloride Solution 4% (available from Morton Grove Pharmaceuticals, Morton Grove, Ill.). The electronically actuated penetrating portion is deployed at a predetermined depth (approximately 3.75 cm to achieve intramuscular delivery in an average adult male deltoid muscle) as lubricant and analgesic flow from the pores in the outer hollow cylinder. Electromechanical devices to insert syringes are described (see e.g., U.S. Pat. No. 8,308,741 and U.S. Pat. No. 6,547,755 which are incorporated herein by reference). For example a micro linear actuator with a range of 50 mm and accuracy of 15 μm is available from Zaber Technologies Inc., Vancouver, B.C., Canada (see e.g., Micro Linear Actuator Spec Sheet available online at http://www.zaber.com/products/product_detail.php?detail=T-NA08A25-SV2 which is incorporated herein by reference). Electromechanical actuators with integrated controllers are also used to drive the outer and inner plungers. After the penetrating portion is inserted the inner plunger is actuated and medicament is delivered intramuscularly. Completion of delivery, as sensed by movement of the actuator leads to retraction of the penetrating portion and transmission of data from the injection system to a central computer. The date, time, location, medicament, dosage, injection site (e.g., deltoid muscle on right arm) are transmitted to a central computer and incorporated in the patient electronic health record.

Prophetic Example 2: An Injection System with Concentric Hollow Cylinders and a Single Plunger to Deliver a Vaccine, Lubricants and Anesthetics at an Injection Site

An injection system is constructed with two concentric hollow cylinders forming a penetrating portion and a single plunger. The outer hollow cylinder is porous and served by a first fluid reservoir portion capped by a deformable membrane and holding a first fluid composition, e.g., lubricants and anesthetic, and the inner hollow cylinder is nonporous and served by a second fluid reservoir portion holding a second fluid composition, e.g., a vaccine or a therapeutic agent (e.g., see FIGS. 19A and 19B). Fluid flow from both reservoirs is controlled by a plunger which applies force directly to the vaccine in the second fluid reservoir portion, and indirectly to the deformable membrane on the first fluid reservoir portion, thereby driving the lubricants and anesthetic from the first fluid reservoir portion and laterally out the porous outer hollow cylinder (see FIG. 22B). The device contains sensors, actuators, microcircuitry and microprocessors to guide the injection and to record and transmit data from the injection.

The injection system includes an outer hollow cylinder which is porous and designed for lateral delivery of lubricants and anesthetics, and an inner hollow cylinder which is coaxial and nonporous for delivery of a second fluid composition, e.g., a vaccine or therapeutic agent. The injection device includes two reservoirs, a first fluid reservoir portion and a second fluid reservoir portion which serve the outer and inner hollow cylinder respectively. The outer hollow cylinder is constructed of a polymer with pores present on the sides of the outer hollow cylinder (see FIGS. 18A and 18B). For example, a microporous polymer of polypropylene may have pores approximately 5 microns in diameter which allow fluid flow (see e.g., U.S. Pat. No. 4,186,745 issued to Lewis et al. on Feb. 5, 1980 which is incorporated herein by reference). In contrast, the inner hollow cylinder is constructed of a nonporous polymer. Methods and materials to construct plastic needles are described (see, e.g., Kim & Colton (2005) J. Med. Eng. Technol. 29:181-186, which is incorporated herein by reference). A substantially ring-shaped first end piece at the penetrating edge is formed from nonporous polymer by injection molding and cast in place to seal the knife edge tip of the injection device, and a flexible substantially ring-shaped second end piece is placed between the inner and outer hollow cylinders in the connector portion of the device to cap the first fluid reservoir portion (see FIGS. 19A and 19B). For example a substantially ring-shaped second end piece of a flexible polymer (e.g., butadiene) may be attached to the inner and outer hollow cylinders with an adhesive or by fusing the end piece to the hollow cylinders with heat or microwaves (see e.g., U.S. Patent Appl. No. 2010/0179478, Ibid.). The first fluid reservoir portion may be filled with lubricant and anesthetic prior to attaching the upper end piece or a syringe may be used to fill the first fluid reservoir portion by injection through the flexible upper end piece. For example the lubricant may be polydimethylsiloxane (available from Dow-Corning, Midland, Mich.) and organosiloxanes (see e.g., U.S. Pat. No. 5,911,711 issued to Pelkey on Jun. 15, 1999, which is incorporated herein by reference), and the anesthetic may be Lidocaine Hydrochloride Solution 4% (available from Morton Grove Pharmaceuticals, Morton Grove, Ill.). The uppermost end of the outer hollow cylinder (i.e., the connector portion; see FIGS. 19A and 19B) may be constructed of nonporous polymer and in the form of a Luer-lock fitting which connects to a syringe with a corresponding Luer-lock male fitting. The syringe barrel forms the second fluid reservoir portion which contains and delivers vaccines and/or therapeutic agents from the sharp edge tip of the penetrating portion when force is applied to the syringe plunger. In addition, fluid pressure on the deformable membrane covering the first fluid reservoir portion drives lubricant and anesthetic from the first fluid reservoir portion through the lateral pores in the outer hollow cylinder. See, e.g., FIG. 19B.

The injection device includes microcircuitry, microprocessors and sensors to detect, record and report injections to a central computer system. For example an accelerometer may detect the motion associated with inserting the penetrating portion in the deltoid muscle of a patient and a pressure sensor may detect the application of force to a syringe plunger. The injection data are recorded by the microprocessor and transmitted to a central computer. For example the sensors may record motion and pressure consistent with injection of a 0.5 mL dose of vaccine intramuscularly. The date, time, patient identification, vaccine lot number, and other information, such as insurance company, healthcare worker, clinic location, are transmitted to a centralized computer (or a cloud computer) and added to the patient's electronic health record.

Prophetic Example 3: An Injection System for Delivery of Medicaments with Two Concentric Hollow Cylinders and Two Reservoirs which Delivers Anesthetics and Lubricants to Reduce the Pain Associated with Intramuscular Injections

An injection device is constructed with two concentric hollow cylinders forming a penetrating portion and two reservoirs which deliver to an injection site a first fluid composition, e.g., lubricants and anesthetics, from a first fluid reservoir portion and a second fluid composition, e.g., a vaccine, from a second fluid reservoir portion. A first fluid reservoir portion is constructed as a flexible bulb which is manually compressed to drive lubricants and anesthetic from the first fluid reservoir portion through pores in an outer hollow cylinder. See FIGS. 29A and 29B. Insertion of the penetrating portion into muscle tissue and initiation of flow of the vaccine from the second fluid reservoir portion is initiated by an automated system which is controlled by microcircuitry and microprocessors on the device.

The injection device with concentric hollow cylinders and two fluid reservoirs is constructed from stainless steel and polymers. The outer hollow cylinder contains pores to allow lateral outflow of analgesics and lubricants which reduce the pain associated with intramuscular injections. For example, the outer hollow cylinder may be fabricated from stainless steel (SS) by pulling heated SS tubes through circular dies to obtain the desired diameter of the hollow cylinder, and then pores may be introduced in the hollow cylinder by micromachining. Penetrating devices with lateral pores are described (see e.g., U.S. Pat. No. 6,517,521 issued to Ly on Feb. 11, 2003, which is incorporated herein by reference), and processes and technologies to manufacture custom syringes and needles are available (see e.g., CregannaInfoSheet from Creganna-Tactx Medical, Campbell, Calif.). For example a 19 gauge (0.686 mm inner diameter), 2.54 cm outer hollow cylinder may be manufactured with approximately 0.050 cm diameter pores spaced approximately 0.08 cm apart for the length of the outer hollow cylinder by micromachining. An inner hollow cylinder, approximately 23 gauge (0.641 mm outer diameter), 3.18 cm long is fabricated for insertion through the smaller spherical reservoir and the outer hollow cylinder (see FIG. 28B). A stainless steel ring-shaped end piece is produced by micromachining and micro-welded to the distal, penetrating end of the inner and outer hollow cylinders and both hollow cylinders are processed by laser cutting and grinding to create a sharp beveled tip (see FIG. 28B). The first fluid reservoir portion is fabricated using injection molding to create a spherical reservoir approximately 6 mm in diameter from flexible polypropylene. The spherical reservoir may have a pressure sensor to detect compression of the spherical reservoir. For example, a Force Sensing Resister is available from Interlink Electronics, Inc., Camarillo, Calif. which signals the microprocessor when the spherical reservoir is squeezed. The spherical reservoir is attached to the top of the outer hollow cylinder and the connector portion of the inner hollow cylinder (see, e.g., FIG. 28B) using adhesives and heat fusion to join the SS and polypropylene components (see e.g., U.S. Patent Appl. No. 2010/0179478, Ibid.). The connector portion of the inner hollow cylinder may be constructed as a Luer-lock fitting which can accept a male syringe fitting. The barrel of the syringe forms the second fluid reservoir portion and the syringe plunger drives flow of fluid from the second fluid reservoir portion through the penetrating end of the inner hollow cylinder for intramuscular delivery of the vaccine. The syringe plunger is actuated by an actuator that is controlled by the microprocessor on the injection system. For example a micro linear actuator with a range of 50 mm and accuracy of 15 μm is available from Zaber Technologies Inc., Vancouver, B.C., Canada (see e.g., Micro Linear Actuator Spec Sheet available online at http://www.zaber.com/products/product_detail.php?detail=T-NA08A25-SV2 which is incorporated herein by reference).

The injection system is assembled after entering health record data into a central computer which communicates with the injection system device. The date, time, location, patient name, medication, route of delivery (e.g., intramuscular), lubricants, anesthetic and health care worker are entered and the appropriate injection system is indicated. For example, an intramuscular injection of an influenza vaccine in an adult male selects an injection system with approximately 0.5 mL of vaccine in the large reservoir (i.e. the syringe barrel) and 0.25 mL of lubricant plus anesthetic in the small reservoir. The injection procedure follows: Holding the injection device near the injection site (e.g., arm) the first fluid reservoir portion is manually compressed forcing anesthetic and lubricant out the plurality of pores along the length of the outer hollow cylinder (see, e.g., FIG. 29A), and the pressure sensor on the first fluid reservoir portion signals the processor to initiate deployment of the penetrating portion and vaccine delivery. The electronically actuated penetrating portion is deployed at a predetermined depth (approximately 3.75 cm to achieve intramuscular delivery in an average adult male deltoid muscle) as lubricant and analgesic flow from the pores in the outer hollow cylinder. Electromechanical devices to insert syringes are described (see e.g., U.S. Pat. No. 8,308,741 and U.S. Pat. No. 6,547,755 which are incorporated herein by reference). Following deployment the microprocessor initiates vaccine delivery by signaling the linear actuator to drive the syringe plunger. Following vaccine delivery the penetrating portion is automatically retracted and the cumulative injection data is transmitted to a central computer.
